8.3.2 Parameter list
The parameters for rotary tables are presented in Table 8.3, and each of the items
in the table is explained in (1) to (9) below.
For details on setting rotary table parameters, refer to the SW2SRX-GSV22PE/
SW0IX-CAMPE Operating Manual.

(1) Number of PULSES per rotary table revolution (N
D
)
(a) This is the setting for the number of PULSES equivalent to one revolution of
the rotary table connected to the servomotor.
Number of PULSES per rotary table revolution (N
D
)
(b) The travel value per revolution is calculated from the number of PULSES
per rotary table revolution in accordance with the following formula:
[Travel per PULSE] =
==
= (degree)
(2) Permissible droop pulse value
(a) This is the setting for the permissible number of droop pulses at the
deviation counter.
(b) The deviation counter value is continually monitored, and if it becomes
larger than the permissible droop pulse value, the error detection signal
(M2407+20n) comes ON.
However, since operation of the roller shaft continues, the user must
execute the appropriate error processing.
(c) When the motor connected has feedback pulses of 131072 PLS, set the
value which is found by dividing the actual permissible droop pulse value by
100.
(3) Stroke limit upper limit value/lower limit value
(a) This is the setting for the stroke range in the virtual mode.
The settings for the stroke limit upper limit value and lower limit value can
determine whether the stroke range is valid or not: if the stroke limit upper
limit value is equal to the stroke limit lower limit value, the stroke limits are
invalid.
(b) If the stroke range is exceeded during operation, the error detection signal
(M2407+20n) comes ON.
However, rotary table shaft stop processing is not executed.
